Patented Dec. 15, 1936 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to improvements in chemical gas mixers to be inserted at the intake manifold of an internal combustion engine and an object of my invention is to provide a mixer which will break up particles of liquid fuel by means of a hardened chemical composition which is introduced into my vaporizer and which I have found possesses the quality of atomizing the fuel particles before they proceed into the combustion chamber.

A further object of my invention is to provide a chemical gas mixer supplied with a baffle which will check the upward stream of gas to the combustion chamber, thereby causing it to be acted upon by the constituents of my composition.

A further object of my invention is to provide a chemical gas mixer having metering jets for the purpose of regulating the amount of air entering the intake manifold.

A further object of my invention is to provide a chemical gas mixer which will decrease the gasoline consumption for a given output of energy in an internal combustion engine.

A further object is to provide a gas mixer which can be easily installed and is economical to manufacture.

A further object of my invention is to provide a chemical gas mixer which will permit the introduction of a greater volume of air and effect complete combustion of the fuel charge, thereby eliminating the exhaustion of carbon monoxide from an internal combustion engine.

With the foregoing objects in view and such other objects as may appear as the description proceeds, my invention consists in the construction and arrangement of parts, all as hereinafter more particularly described, reference being had to the accompanying drawing, in which:-

Fig. 1 shows my chemical gas mixer in perspective with the bafile partially broken away.

Fig. 2 is a plan view of my chemical gas mixer.

Fig. 3 is a sectional elevation of my chemical gas mixer taken upon the line 22 of Figure 2.

In the drawing like characters of reference indicate corresponding parts in the different figures.

My invention consists of a metallic gasket A having orifices i8 drilled at either end thereof and an enlarged central aperture B, and is designed for insertion within the intake manifold (not shown) of an internal combustion engine, just above the carburetor.

A circular perforated bafiie C covers the central aperture and is spaced a distance thererrom by means of upstanding lugs l I located upon the periphery of the central aperture. An annular channel [2 is recessed around the central aperture B and is packed flush up to the outer edges of the annular channel with a chemical composition l3 composed of a powdered carbon such as graphite, naphthalene and a suitable binding material such as pitch. This composition is inserted in a plastic condition and is then allowed to set hard.

A circular passageway Id is provided in the composition against the channel l2 and a plurality of radially disposed orifices I5 are punctured through the composition-to connect with the circular passageway.

Upon the outer edges of the gasket, I locate two metering jets l6 substantially opposed to each other but slightly offset. These metering jets are of well known design and consist: of a screw threaded stem I! having acentrally disposed channel I 8 running lengthwise therethrough and perpendicular channels l9 connecting therewith and with the atmosphere.

A screw 20 having a needle valve 2| located at one end thereof, engages with the stem and is provided with an encircling spring washer 22. The orifice, into which the stem of the metering jet is received, is tapped and extends clear through the gasket to the rear wall of the annular channel I2. From the foregoing. it will be seen that a controllable air jet may be drawn into the circular passageway l4 and from thence through the radial orifices [5 into the manifold.

I have mentioned that my device prevents carbon monoxide. This is due to the fact that complete combustion of the fuel takes place within the compression chamber and it is well known that carbon monoxide is only formed in combination with unburned fuel within the compression chambers.

In operation, I have found that the gasoline from internal combustion engines fitted with my gas mixer, when drawn into the engine by the intake stroke of the pistons, is partially retarded by the baffie and is acted upon by the composition in such a manner as causes it to become completely vaporized before proceeding upwards to the compression chambers.

The use of my device upon automobiles particularly, has resulted in a consistent and very marked increase in the mileageof the automobile so fitted and has not diminished the power of the engine to the slightest extent.

Since various modifications can be made in the above invention, and many apparently widely different embodiments of same, made within the scope of the claims without departing from the spirit and scope thereof, it is intended that all matter contained in the accompanying speciflcation shall be interpreted as illustrative only and not in a limiting sense and I desire only such limitations placed thereonas are specifical- 1y expressed in the accompanying claims.

What I claim as my invention is:

1. Improvements in gas mixers, comprising a body portion having an enlarged orifice extending therethrough, an annular channel upon the periphery of said orifice, air metering jets extending through said body portion to said channel and a hardened chemical composition within said channel composed of carbon, naphthalene and a binding substance, said composition being provided with a plurality of orifices connecting with said air metering jets.

2. Improvements in gas mixers, comprising a body portion having an enlarged orifice extending therethrough, an annular channel upon the periphery of said orifice, air metering jets extending through said body portion to said orifice, a hardened chemical composition within said channel and extending therearound and composed of carbon, naphthalene, and a binding substance, said chemical composition having a circular passageway extending therethrough connecting With said air metering jets and being provided with a plurality of orifices which extend from said circular passageway.

3. The device as claimed in claim 2, in which bafiiing means are attached to said body portion.
